I see this error in your log:

Unable to connect to Gunvor. Is it running? [http://localhost:8080/drools-guvnor/org.drools.guvnor.Guvnor/oryxeditor?uuid=9c7c6c9f-1b2e-48cc-8e33-719eace1c139&usr=admin&pwd=admin]

So, the first question would be: is Guvnor running in this URL http://localhost:8080/drools-guvnor/org.drools.guvnor.Guvnor/?

I know that Guvnor's URL changed some time ago, but I think that for 5.3 Final that is the correct URL.

Best Regards,

Thanks Tihomir for your reply.

I am using Guvnor(Guvnor-5.3.0.Final-jboss-as-5.1.war), Designer(designer-2.0-jboss.war), Jboss As(jboss-5.1.0.GA). I created simple process which consist of start node, task node and end node.
I am also attaching screen shot of bpmn process and server log file.
Thanks in advance.

Thanks and regards,
Manohar Kokkula

Manohar, I would love to help you guys up and running with the jBPM Designer. Do appreciate the interest in using it, that's great, but don't know how unless you show logs, specify versions of Designer, Guvnor, jBPM, and the AS, describe your process (screenshot, bpmn2..), etc.
Getting the blank canvas currently means that the generated BPMN2 from Designer for your particular process is not valid for some reason. Providing more info what what you are doing can help us. The logs should indicate exactly why parsing of the generated BPMN2 failed, so with that info and what i mention above we should be able to figure out the problem.
I'm working on showing errors/warnings on saving the process in the designer itself, so this should help .. will be available in 2.1.

Can you replace your designer war with one from here:http://people.redhat.com/tsurdilo/designer/master/ and let me know if you still run into this? Thanks.
